What are the key electrical specifications?

It features a typical impedance of 1000 Ohms at 100 MHz, a maximum DC resistance of 0.8 Ohms, and a rated current of 200 mA.

What package size is this component?

It comes in a standard 0603 (1608 metric) surface-mount package, measuring 1.6 mm x 0.8 mm x 0.8 mm.

What is the operating temperature range?

The component is rated for operation between -55°C and +125°C.

Is this component suitable for power lines?

No, this specific 'RK' series is intended for digital interfaces. For DC power lines, Murata offers 'PG' or 'KG' series ferrite beads with higher current ratings.

What should sourcing teams check before buying BLM18RK102SN1D?

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: Low; readiness: easy.

What is the pinout of BLM18RK102SN1D?

Use the BLM18RK102SN1D datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about BLM18RK102SN1D pinout to locate pins, power rails, and interface signals before layout.
